BURNER-IGNITER.

To all whom it may concern:

Be it known that I, l/VILLIAM J. Bnsr, a citizen of the United States,and a resident of Detroit, in the county of \Vayne and State ofMichigan, have invented a new and Improved Burner-Igniter, of which thefollowing is a specification.

This invention relates to gas-stove ovens of the general type shown inthe Simpson Patent No. 722,414, dated March 10, 1903, and in the BestPatent No. 979,418, dated Dec. 27 1910, and its object is to providemeans for the ignition of the gas issuing from one burner-tube from theflame of the other.

This invention consists in a flame conductor extending across betweenthe burner tubes of gas-stove ovens, and comprises a pipe of any desiredcross-section having a hood at each end extending over gas-openings in aburner-tube and an opening in this conductor intermediate its ends forthe escape of the air.

In the accompanying drawing, Figure 1 is a central vertical section ofan oven embodying this invention. Fig. 2 is a horizontal section on theline 2-2 of Fig. 1. Fig. 3 is a vertical section on the line 33 of Fig.2. Fig. 4 is a front elevation of the flame conveyer. Fig. 5 is a crosssection of the conductor at the escape opening.

Similar reference characters refer to like parts throughout the severalviews.

The drawings show a range casing having a top 1, back 2, sides 3, bottom4 and front door WVithin the range is an oven comprising a top 6, aperforated bottom 7, a back 8, and sides 9. The sides and back may beseparated from the casing by air spaces. The casing has an inner plate10 below the top 1, from which the top of the oven may be separated byan air space. Projecting upwardly from the casing bottom 4 are theplates 12 which carry guides 13 in which the oven bottom 7 is slidable.

Within the oven are removable flues comprising upright ends 15, outerplates 16, and longitudinal plates 17 and 18. The longitudinal plates 17have in-turned ribs 19 to support shelves 20 and the out-turned flanges21 to cause a portion of the rising burned gases and hot air to enterthe oven below these flanges. The plates 18 have similarshelf-supportingribs 22 and between their lower edges and the plates 16 are thedefiector plates 23 having down-turned flanges Specification of LettersPatent.

24. The pipe 26 extends horizontally between the bottoms 4 and 7, theinlet end being preferably about midway between the front and rear rowsof perforations 27 in the plate 7. The pipe may extend in any desireddirection after leaving the range. Burner tubes 28 extend horizontallybetween the plates 12 and the sides 9 and have holes 29 for the passageof the gas. They connect at their front ends to the cross pipe 30,which, in turn, is connected to and supplied by the feed pipe 81. Anydesired connection may he had between the pipe 31 and the source of gassupply.

The flame conductor may be transversely positioned at any point on thetubes 28, but is preferably located at the front of the oven. Betweenthe bottoms 4 and 7, and between the plates 12 which support the bottom7 is an upright plate 35, which is parallel to the front plate 36 of thecasing. Within the small chamber thus formed, and below the bottom 7 ofthe oven, are the gas pipes 30 and 31, and the flame conduct-or whichconstitutes the present invention. This conductor is a horizontal bodyof any desired cross section, having hoods extending over perforationsin the burner pipes so that the body may fill with an explosive mixture.The preferred construction is shown in Figs. 4 and 5.

Two strips of sheet metal may be properly pressed to form the conductor.The upper portion consists of a longitudinal top 40 having downwardlycurved ends 41 to form hoods, and sides 42, having the feet 43 adaptedto rest on the cross pipe 30. The lower portion of the conductor isformed of a flat plate 44 and small lugs or feet 45 secured to the feet43. This plate 44 forms the bottom of the flame conductor, and itslength is so much less than the upper portion that spaces are left atthe ends of the conductor, immediately over burner openings in theburner tubes 28. An opening 47, intermediate the ends of the conductor,preferably in its bottom, permits the escape of the air within the tube.

When gas is turned on, it will flow through the pipes 31 and 30 and outof the perforations 29. It immediately rises and may be ignited at anopening A at either side of the oven. When the gas at one side only islighted, as has happened because of the ignorance or absent-mindednessof the cook, the gas from the other side soon fills the oven and anexplosion results. The flame conductor shown in the drawings permitsmixed gas and air to pass from the openings 29 under the ends 41, up andinward toward the opening 47 through which the air escapes. When the gasat one side is ignited, a flame of explosion runs through the body ofthe conductor and immediately ignites the gas at the other side of theoven. As this flame conductor is inclosed except at its ends, there isno danger of injury to the person lighting the burners. The design andproportions of this conductor may be varied to meet the requirements ofother designs of burners.

Having now explained my construction, what I claim as my invention anddesire to secure by Letters Patent is 1. In a gas stove, the combinationwith a plurality of burner tubes having gas openings, of a flameconductor extending above and across between the tubes and comprising ahollow tubular body having openings in its bottom at the points where itextends over openings in the burner tubes and means to position it abovesaid tubes, said body having an opening intermediate its ends to permitthe escape of air so as to permit the passage of gas from both of theburner tubes.

2. In a gas stove, the combination with a plurality of burner tubeshaving gas openings, of a flame conductor extending across between thetubes and comprising a bottom, sides and top, the top having downwardlyinclined ends to form hoods over the tubes, the bottom ending short ofthe tubes to leave openings above the tubes for the admission of gasfrom openings in the tubes, and the sides connecting the top and bottomand formed with feet to support the flame conductor, said conductorhaving an opening in its bot-tom intermediate the ends to permit theescape of air so as to permit the passage of gas from both of the burnertubes.

In testimony whereof I have signed this specification 'in the presenceof two subscribing witnesses.
